How to deal with leakage through the partition wall 1.5 meters above the bottom of the vertical flue
It is treated by the heat repair technician using spray patching or troweling methods as appropriate.
On the upper part of the partition wall in the vertical flue?
Leakage through the partition wall of the vertical flue? Exactly where is it, and how severe is the damage? What caused it, what type of furnace is it, and how old is the furnace? In any case, it is best not to use wet spray repair, as it causes too much damage to the furnace wall.
About 1.5 meters from the firebox partition wall. It is not large in size, with a diameter of about 10 MM. It is a JN4380 type coke oven. The stove has only been in use for a little over a year. There could be two reasons: 1. The flame is too large, causing combustion near the furnace wall. 2. It may be due to quality issues in the construction of the coke oven.
At about 1.5 meters from the partition wall of the vertical flue, it is very likely due to excessive temperatures; this area is probably where the temperature in the vertical flue is highest. What was said about \"a life of a few drinks\" is true – wet spraying repair isn’t feasible, after all, it’s only been a year since the furnace was installed.
Is the situation described by the poster common? If it is an isolated phenomenon, I believe there is no need to take action, as it will not have a significant impact on heating. The principle of thermal repair is to use dry methods whenever possible instead of wet ones ； It can be repaired without spraying or patching ； Fix it only if necessary; don’t overfix it ； (If possible, avoid repairs for now; see if it can get caught by the stone mill.)
Is it connected to that area, is it the partition wall between the vertical flues that serves as the connection, or is it the wall of the carbonization chamber that forms the connection?
It is a leakage between vertical flues, that is, the partition wall of the vertical flues (the main flue wall), which separates two flues with air currents flowing in opposite directions.
I agree with the views of those above; let the stones grind against each other on their own, as long as heating is not affected and high temperatures are not generated. If it must be treated, a spray of slurry can be applied.
Isn’t it difficult to perform spray repair on a 10-millimeter hole? It should be simply patched up first, and then treated with shotcrete.
